High humidity can reduce the mechanical properties of materials by promoting corrosion, causing swelling or warping in certain materials, and reducing the strength and durability of some materials over time. Water molecules can weaken the bonds between atoms in materials, leading to a decrease in mechanical properties such as strength, stiffness, and toughness.
Forging significantly enhances the mechanical properties of metals by refining their microstructure, which leads to improved strength, toughness, and ductility. The process aligns the grain structure in the direction of the applied stress, resulting in increased resistance to fatigue and failure. Additionally, forging can eliminate defects and inclusions, further contributing to the overall integrity and performance of the material. As a result, forged metals often exhibit superior mechanical characteristics compared to their cast or machined counterparts.

Yes, the higher the humidity, the more chance of rain. 80-100% of humidity is rain.
In the piezoelectric effect, mechanical stress applied to certain materials causes a displacement of charge within the material, resulting in the generation of an electrical voltage. This occurs because the stress alters the positions of positive and negative charge centers, leading to an imbalance that produces an electric field. When the material is deformed, electrons in the crystal lattice shift, allowing for the conversion of mechanical energy into electrical energy. Conversely, applying an electric field can induce mechanical deformation in piezoelectric materials.
Radiation can cause damage to materials by disrupting their atomic structure, resulting in changes to their physical and chemical properties. This can include degradation of mechanical strength, modification of electrical properties, and altering of surface characteristics. In severe cases, radiation can lead to material failure or breakdown.
Humidity is a mayor factor in thing drying. Needles to say a porous material is likely to have water within it and therefore will dry more slowly. However regardless of the material high humidity at the time will slow down the drying process and low humidity will speed it up.

thermodynamic is the branch of science which deals with the energy transfer and its effect on the physical properties of the material
The reduction of the diameter of a stainless steel bar by hot or cold work will usually increase the strength and lower the elongation. However after the normal annealing the mechanical properties will be about the same as before it was reduced in diameter. If the reduction is by machining, the properties will remain the same unless it is overheated.

Friction welding of ferrous materials can improve their mechanical properties by creating a strong bond at the molecular level through localized heating and plastic deformation. This process can enhance the tensile strength and fatigue resistance of the welded joint, resulting in a reliable and durable connection. Proper control of the welding parameters is essential to ensure the desired mechanical behavior in the welded ferrous material.
